SMUT-MACHIN'E.

Specification of Letters Patent No. 2,291, dated October 9, 1841.

To ati whom i may concern Be it known that I, Lnwrs GREENE, of Tiflin, in the County of Seneca and State of Ohio, have invented an Improvement in the Manner of Constructing' Smut-Machines or Machines for Cleaning' lVheat or other Grain; and I do hereby declare that the followng' is a full and exact description thereof.

I construct a frame which is to sustain a vertical, hollow cylinder, or case, that may be of cast-iron, or other mat-erial. Through the center of this cylinder passes a vertical shaft which carries a revolving rubber at its upper end, said rubber consisting' of a flat disk of cast-iron having' teeth cast upon its upper side, rang'ed in regular circles, said teeth when set in motion passing` between similar rows of teeth on a stationarv disk of cast-iron, sustained on the upp-er end of the cylinder, or case, of the machine. Through an opening in the center of this upper disk, and surrounding' the shaft, the grain is to be fed into the machine. The shaft which carries the revolving 'disk carries also four arms near to its upper, and four others near to its lower end, within the cylinder. These arms eXtend nearly to the periphery of the cylinder, and sustain iron rods which pass vertically from Vone of the lower to one of the upper arms; there being' four sets of such rods, each set usually consisting` of eig'ht rods made of square iron. about half an inch in diameter, and standing` at the distance of about half an inch from each other. The shaft carrying these rods, or beaters, is to be made to revolve with g'reat rapidity, say with a speed of four liundred revolutions in a minute, and the grain in falling' from the upper to the lower end of the machine, is forcibly bea-ten by them against the interior of the cylinder, the surface of which is plain, and without perforations.

In the accompanying drawing, Figure l, is a vertical section of the machine through its center. A, A, is the cylinders, or case, and B, the revolving shaft. C, is the disk attached to said shaft at its upper end, and armed with teeth on its upper side for rubbing' the grain. D, is the upper, or stationary, disk between which and the disk C, the rubbing' is to be effected.

E, FX, are two of the arms, carrying' the beaters a, a, a.

Fig'. 2, is a top view of the disk C, with the Circular rows of teeth 0,1), upon it, which teeth fit into the spaces between similar teeth on the disk D, there being sufficient room between the rows of teeth to admit of the passag'e of the grain, which is forciblv rubbed in its transit from the feeding opening' c, c, in the middle of the upper disk, until it falls over the edges of the disk C, and is encountered by the beaters. F, is a whirl by which the shaft may be made to revolve, and G, a bridge tree, Operating' in the usual way. After passing' through this machine, the grain is to be cleaned by means of the o-rdinary fanning mill. I

Having' thus fully described the manner in which I construct my machine, and shown the operation thereof, what I claim therein as new, and desire to secure by Letters Patent, ise- The mode in which I have combined the stationary and the revolving` disks, furnished with teeth upon their surfaces, with the revolving' arms carrving' square, vertical rods of iron; the whole being' arrang'ed, combined, and Operating, as above set forth.

LEVVIS GREENE.
